Abstract:
The present disclosure is directed to a method of welding a gasket to a spigot portion of a pipe section. The method includes supporting the gasket in a recess on the spigot portion of the pipe section. The gasket includes a seating portion and a sealing portion. The sealing portion includes a first shoulder portion and a second shoulder portion. A first bonding portion extends from the first shoulder portion and a second bonding portion extends from the second shoulder portion. The first bonding portion and the second bonding portion are provided to bond the gasket to the spigot portion. The method further includes heating a portion of the gasket and an adjacent surface of the spigot portion and applying a force onto the portion of the gasket following the application of heat to fuse the gasket onto the spigot portion.
Abstract:
A corrugated pipe manufacturing cell is configured to produce multiple corrugated pipes in parallel. The manufacturing cell may comprise an extrusion system that is capable of providing multiple independently regulated flows of plastic piping material to multiple die heads. The multiple die heads may feed a set of mold blocks having dual cavities for forming he multiple corrugated pipes. The pipe manufacturing cell may be converted between a first mode for producing large diameter single corrugated pipes, and a second mode for producing smaller diameter, plural corrugated pipes.
Abstract:
This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.
Abstract:
Stormwater management systems, methods, and apparatuses for containing and filtering runoff may be provided. In one implementation, a flared end ramp for managing flow of material into a stormwater chamber may be provided. The flared end ramp may include an inlet end configured for connection with a pipe, a side wall of the flared end ramp having a rounded profile at the inlet end; an outlet end configured for placement within the stormwater chamber; and an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber. The outlet end of the flared end ramp may have a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end.
